After reading the example from
http://www.lpcware.com/system/files/lpcopen_v2_00a_lpcxpresso_nxp_lpcxpresso_11c24.zip
above (very quickly):
- The CAN-API is used, but no RAM is reserved for it? RAM from 0x1000 0050 to 0x1000 00B8.
- /* Send a simple one time CAN message */
msg_obj.msgobj = 0;
I think msobj 0 doesn't exist. It's range is 1 to 32.

You should be able to fix this yourself by adding the following definition to the code:
__BSS(RESERVED) char CAN_driver_memory[256] ; // reserve 256 bytes for CAN driver
For more details, see:
